Any Sound Card Recommendations?

[Thomas George <lists@tomgeorge.info>]

I bought an Asus Xonar DSX expecting it to work with my Debian Stretch 
system, there was a recommendation on the Internet from someone using 
Mint who said it worked right out of the box. Mine didn't.

I would like a really good sound card for my system and don't want to 
make the same mistake twice.

Any recommendations?
